Home / Checking port optical signals on Huawei switches
Run the display transceiver [ interface interface-type interface-number | slot slot-id ] [ verbose ] command to view information about the optical module on a specified interface. During use, reading optical module information helps understand its real-time operating status, enabling faster troubleshooting of link abnormalities. Transceiver Type : 1000 _BASE_SX_SFP Connector Type :LC Wavelength(nm) : 850 Transfer Distance(m) : 300 (50 um), 150.
The following uses the Moduletek SFP-10G-LR module connected to a Huawei S6700 switch as an example to introduce how to read information of the connected optical module on a Huawei switch.
